Virtual Reality Games for Motor Rehabilitation

This paper presents a fuzzy logic based method to track user satisfaction without the need for devices to monitor users physiological conditions. User satisfaction is the key to any product’s acceptance; computer applications and video games provide a unique opportunity to provide a tailored environment for each user to better suit their needs. We have implemented a non-adaptive fuzzy logic model of emotion, based on the emotional component of the Fuzzy Logic Adaptive Model of Emotion (FLAME) proposed by El-Nasr, to estimate player emotion in UnrealTournament 2004. In this paper we describe the implementation of this system and present the results of one of several play tests. Our research contradicts the current literature that suggests physiological measurements are needed. We show that it is possible to use a software only method to estimate user emotion

Emergence of integrated institutions in a large population of self-governing communities

Most aspects of our lives are governed by large, highly developed institutions that integrate several governance tasks under one authority structure. But theorists differ as to the mechanisms that drive the development of such concentrated governance systems from rudimentary beginnings. Is the emergence of integrated governance schemes a symptom of consolidation of authority by small status groups? Or does integration occur because a complex institution has more potential responses to a complex environment? Here we examine the emergence of complex governance regimes in 5,000 sovereign, resource-constrained, self-governing online communities, ranging in scale from one to thousands of users. Each community begins with no community members and no governance infrastructure. As communities grow, they are subject to selection pressures that keep better managed servers better populated. We identify predictors of community success and test the hypothesis that governance complexity can enhance community fitness. We find that what predicts success depends on size: changes in complexity predict increased success with larger population servers. Specifically, governance rules in a large successful community are more numerous and broader in scope. They also tend to rely more on rules that concentrate power in administrators, and on rules that manage bad behavior and limited server resources. Overall, this work is consistent with theories that formal integrated governance systems emerge to organize collective responses to interdependent resource management problems, especially as factors such as population size exacerbate those problems.Comment: contains supplemen

Vocabulary Learning Perceptions and Willingness to Communicate: A Comparison of Two Video Game Genres

This MA thesis examined the differences in vocabulary leaning perceptions and willingness to communicate (WTC) of players of two video game genres: the players of First Person Shooter (FPS) games, and the players of Massively Multiplayer Online Role-Playing (MMORPG) games. The aim of this thesis was to ascertain which target group of video game-players perceived their genre to be more useful or conducive to incidentally learning vocabulary and how their genre affected their WTC. The data for the comparison were gathered using an anonymous online questionnaire created on the Webropol website. The questionnaire consisted of three sections: the background information section, the WTC section, and the vocabulary section. A total number of 43 participants took part in the questionnaire. This number of participants was adequate to apply quantitative methods to the results of the questionnaire. Questionnaire answers were given simple scores and compared using Microsoft Excel and the IBM SPSS statistics program. In both sections of the questionnaire, the MMORPG group outscored the FPS participant group. An Independent Samples T-test found there to be significant differences (p=.027) in the WTC section, but no significant differences (p=.245) were found in the vocabulary section. Nonetheless, the vocabulary section did provide results that skewed in favour of the MMORPG participants in a similar manner to the WTC section. The results of this thesis indicate that MMORPGs are better suited for these two facets of language learning. While previous research has highlighted the benefits of MMORPGs for language learning, no direct comparison has been made with other video game genres. Future research could focus on comparing additional genres to MMORPGs or different genres

The Industry and Policy Context for Digital Games for Empowerment and Inclusion:Market Analysis, Future Prospects and Key Challenges in Videogames, Serious Games and Gamification

The effective use of digital games for empowerment and social inclusion (DGEI) of people and communities at risk of exclusion will be shaped by, and may influence the development of a range of sectors that supply products, services, technology and research. The principal industries that would appear to be implicated are the 'videogames' industry, and an emerging 'serious games' industry. The videogames industry is an ecosystem of developers, publishers and other service providers drawn from the interactive media, software and broader ICT industry that services the mainstream leisure market in games, The 'serious games' industry is a rather fragmented and growing network of firms, users, research and policy makers from a variety of sectors. This emerging industry is are trying to develop knowledge, products, services and a market for the use of digital games, and products inspired by digital games, for a range of non-leisure applications. This report provides a summary of the state of play of these industries, their trajectories and the challenges they face. It also analyses the contribution they could make to exploiting digital games for empowerment and social inclusion. Finally, it explores existing policy towards activities in these industries and markets, and draws conclusions as to the future policy relevance of engaging with them to support innovation and uptake of effective digital game-based approaches to empowerment and social inclusion.JRC.J.3-Information Societ

Virtual environments promoting interaction

Virtual reality (VR) has been widely researched in the academic environment and is now breaking into the industry. Regular companies do not have access to this technology as a collaboration tool because these solutions usually require specific devices that are not at hand of the common user in offices. There are other collaboration platforms based on video, speech and text, but VR allows users to share the same 3D space. In this 3D space there can be added functionalities or information that in a real-world environment would not be possible, something intrinsic to VR. This dissertation has produced a 3D framework that promotes nonverbal communication. It plays a fundamental role on human interaction and is mostly based on emotion. In the academia, confusion is known to influence learning gains if it is properly managed. We designed a study to evaluate how lexical, syntactic and n-gram features influence perceived confusion and found results (not statistically significant) that point that it is possible to build a machine learning model that can predict the level of confusion based on these features. This model was used to manipulate the script of a given presentation, and user feedback shows a trend that by manipulating these features and theoretically lowering the level of confusion on text not only drops the reported confusion, as it also increases reported sense of presence. Another contribution of this dissertation comes from the intrinsic features of a 3D environment where one can carry actions that in a real world are not possible. We designed an automatic adaption lighting system that reacts to the perceived user’s engagement. This hypothesis was partially refused as the results go against what we hypothesized but do not have statistical significance. Three lines of research may stem from this dissertation. First, there can be more complex features to train the machine learning model such as syntax trees. Also, on an Intelligent Tutoring System this could adjust the avatar’s speech in real-time if fed by a real-time confusion detector. When going for a social scenario, the set of basic emotions is well-adjusted and can enrich them. Facial emotion recognition can extend this effect to the avatar’s body to fuel this synchronization and increase the sense of presence. Finally, we based this dissertation on the premise of using ubiquitous devices, but with the rapid evolution of technology we should consider that new devices will be present on offices. This opens new possibilities for other modalities.A Realidade Virtual (RV) tem sido alvo de investigação extensa na academia e tem vindo a entrar na indústria. Empresas comuns não têm acesso a esta tecnologia como uma ferramenta de colaboração porque estas soluções necessitam de dispositivos específicos que não estão disponíveis para o utilizador comum em escritório. Existem outras plataformas de colaboração baseadas em vídeo, voz e texto, mas a RV permite partilhar o mesmo espaço 3D. Neste espaço podem existir funcionalidades ou informação adicionais que no mundo real não seria possível, algo intrínseco à RV. Esta dissertação produziu uma framework 3D que promove a comunicação não-verbal que tem um papel fundamental na interação humana e é principalmente baseada em emoção. Na academia é sabido que a confusão influencia os ganhos na aprendizagem quando gerida adequadamente. Desenhámos um estudo para avaliar como as características lexicais, sintáticas e n-gramas influenciam a confusão percecionada. Construímos e testámos um modelo de aprendizagem automática que prevê o nível de confusão baseado nestas características, produzindo resultados não estatisticamente significativos que suportam esta hipótese. Este modelo foi usado para manipular o texto de uma apresentação e o feedback dos utilizadores demonstra uma tendência na diminuição do nível de confusão reportada no texto e aumento da sensação de presença. Outra contribuição vem das características intrínsecas de um ambiente 3D onde se podem executar ações que no mundo real não seriam possíveis. Desenhámos um sistema automático de iluminação adaptativa que reage ao engagement percecionado do utilizador. Os resultados não suportam o que hipotetizámos mas não têm significância estatística, pelo que esta hipótese foi parcialmente rejeitada. Três linhas de investigação podem provir desta dissertação. Primeiro, criar características mais complexas para treinar o modelo de aprendizagem, tais como árvores de sintaxe. Além disso, num Intelligent Tutoring System este modelo poderá ajustar o discurso do avatar em tempo real, alimentado por um detetor de confusão. As emoções básicas ajustam-se a um cenário social e podem enriquecê-lo. A emoção expressada facialmente pode estender este efeito ao corpo do avatar para alimentar o sincronismo social e aumentar a sensação de presença. Finalmente, baseámo-nos em dispositivos ubíquos, mas com a rápida evolução da tecnologia, podemos considerar que novos dispositivos irão estar presentes em escritórios. Isto abre possibilidades para novas modalidades

Designing for mod development: user creativity as product development strategy on the firm-hosted 3D software platform

The thesis is designed to improve our understanding of user participation in Web-based development practices in the commercial setting of the 3D software industry. It aims to investigate whether the creative capacities of users and their contributions to the online firm-hosted 3D platform are indicative of a novel configuration of production that influences the processes of product development across firm boundaries. The thesis mobilizes the user participation literature developing in media research as its main theoretical framework. It builds on insights derived from work on user participation in media sites as seen through a cultural lens, in particular, as developed in Henry Jenkins' notions of 'participatory' and 'convergence culture'. The user participation literature is supported by a combination of insights drawn from work on communities of practice and user-centred innovation so as to offer a more robust approach to examine and appreciate the firm-hosted 3D platform as a site of user participation. More specifically, the conceptual framework for the study provides a basis for an examination of the ways a software developer finn encourages user participation in a market and of how this enables and facilitâtes particular modes of user creativity. These are shown to shape and maintain a firm-hosted platform that aids product development efforts that are expected to benefit the developer fimi. An empirical study of the platform, Second Life, provides the basis for the analysis of finn-user interactions which are shown to underpin a distinctive finn leaming process in the context of product development that occurs across permeable fimi boundaries. The thesis yields insight into the way a developer firm invites its user base to partner with it in product development, indicating how aspects of user participation associated with non-market dynamics are embedded in commercial activity and professionalism. The pivotal role of users is revealed in the design, development and sustainability of a firm-hosted 3D product. The findings point to interesting relationships between the distinctive creative capacities of users and the range of capabilities afforded by the firm-provided design space. Variations in user participation and contributions to product development suggest that particular patterns of learning opportunities occur. The analysis yields several new concepts including a 'modification effect market' which are used to extend existing conceptualizations of user participation in digitai development practices in the commercial setting of the 3D software industry
